According to this: https://bugs.launchpad.net/ubuntu/+source/rss-glx/+bug/537011 need to run /usr/bin/rss-glx_install, which will look at existing ~/.xscreensaver and add any missing entries. However this file missed in rss-glx. OR manually add the following lines after the line that starts with "programs:" in ~/.xscreensaver. -- Cut Here -- GL: "Cyclone" cyclone --root \n\ GL: "Euphoria" euphoria --root \n\ GL: "Fieldlines" fieldlines --root \n\ GL: "Flocks" flocks --root \n\ GL: "Flux" flux --root \n\ GL: "Helios" helios --root \n\ GL: "Hyperspace" hyperspace --root \n\ GL: "Lattice" lattice --root \n\ GL: "Plasma" plasma --root \n\ GL: "Skyrocket" skyrocket --root \n\ GL: "Solarwinds" solarwinds --root \n\ GL: "Colorfire" colorfire --root \n\ GL: "Hufo's Smoke" hufo_smoke --root \n\ GL: "Hufo's Tunnel" hufo_tunnel --root \n\ GL: "Sundancer2" sundancer2 --root \n\ GL: "BioF" biof --root \n\ GL: "BusySpheres" busyspheres --root \n\ GL: "SpirographX" spirographx --root \n\ GL: "MatrixView" matrixview --root \n\ GL: "Lorenz" lorenz --root \n\ -- End Here -- I've added the above lines however these screensavers still not listed. I see different data paths in xscreensaver-data (/usr/libexec/xscreensaver) package and in rss-glx (/usr/lib64/xscreensaver) - may be that is the problem? Also .desktop files missed in rss-glx.
